      block/nfs: Add create_opts · fd752801
      由 Max Reitz 提交于 
      The nfs protocol driver is capable of creating images, but did not
specify any creation options. Fix it.

A way to test this issue is the following:

$ qemu-img create -f nfs nfs://127.0.0.1/foo.qcow2 64M

Without this patch, it segfaults. With this patch, it does not. However,
this is not something that should really work; qemu-img should check
whether the parameter for the -f option (and -O for convert) is indeed a
format, and error out if it is not. Therefore, I am not making it an
iotest.

      block: Use g_new() & friends where that makes obvious sense · 5839e53b
      由 Markus Armbruster 提交于 
      g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

Patch created with Coccinelle, with two manual changes on top:

* Add const to bdrv_iterate_format() to keep the types straight

* Convert the allocation in bdrv_drop_intermediate(), which Coccinelle
  inexplicably misses

      block: add native support for NFS · 6542aa9c
      由 Peter Lieven 提交于 
      This patch adds native support for accessing images on NFS
shares without the requirement to actually mount the entire
NFS share on the host.

NFS Images can simply be specified by an url of the form:
nfs://<host>/<export>/<filename>[?param=value[&param2=value2[&...]]]

For example:
qemu-img create -f qcow2 nfs://10.0.0.1/qemu-images/test.qcow2

You need LibNFS from Ronnie Sahlberg available at:
   git://github.com/sahlberg/libnfs.git
for this to work.

During configure it is automatically probed for libnfs and support
is enabled on-the-fly. You can forbid or enforce libnfs support
with --disable-libnfs or --enable-libnfs respectively.

Due to NFS restrictions you might need to execute your binaries
as root, allow them to open priviledged ports (<1024) or specify
insecure option on the NFS server.

For additional information on ROOT vs. non-ROOT operation and URL
format + parameters see:
   https://raw.github.com/sahlberg/libnfs/master/README

Supported by qemu are the uid, gid and tcp-syncnt URL parameters.

LibNFS currently support NFS version 3 only.
